How it works
We read your page twice, then measure the difference
The gap between what a visitor sees and what a machine receives is where most sites quietly lose visibility in AI search.
- Step 1
Fetch as an AI crawler
We request your page as plain code with no JavaScript run, exactly the way GPTBot, ClaudeBot, and PerplexityBot receive it.
- Step 2
Render as a human
We load the same page in a real browser that runs everything, so we have the full version a visitor actually sees.
- Step 3
Score the gap
We measure the difference across the six pillars and combine it into one grade from A to F, weighted by what matters most to AI systems today.
The basics
What is an AI website scanner?
An AI website scanner checks how AI crawlers and AI search systems access, read, understand and use your website. Unlike a traditional SEO audit, it looks at crawler access, JavaScript-rendered content, structured data, citability, navigation and machine-readable content, then grades how well AI can work with your page.
It complements your SEO. Classic SEO gets you ranked for people to click. AI search visibility decides whether AI systems can read and cite you when they answer. You want both.
Technical website auditing software
Know what AI search sees, and fix what holds you back.
Siteiz audits your website for AI search readiness, finds the problems that make your content harder for AI systems to understand, and gives you the exact fixes.

AI visibility
44 / 100
Looks great in a browser, mostly empty to a crawler.
Can AI crawlers see your content?
How much of what people see is in the HTML a crawler receives, before any JavaScript runs.
- Text and headings that only appear after JavaScript
- Prices that vanish from the raw HTML
- Empty app shells, missing H1, images without alt text
Adds 6 of its 30 possible points.
Can an AI agent follow links and act?
Whether an agent can follow your links, menus and calls to action without a mouse.
- Links missing from the raw HTML
- Navigation that only works with JavaScript
- Calls to action and form fields an agent cannot use
Adds 7 of its 20 possible points.
Can machines understand what the page is?
Structured data and metadata that tell AI what your page is and what it offers.
- Valid JSON-LD entities, or none at all
- Generic titles and boilerplate meta descriptions
- Prices and offers not backed by structured data
Adds 8 of its 20 possible points.
Can AI crawlers reach the page?
Whether AI crawlers are allowed in, and whether anything quietly blocks them.

Adds 15 of its 15 possible points.
Can a machine process the page efficiently?
How much markup a machine wades through per useful word. Bloated pages get truncated.

Adds 5 of its 10 possible points.
Can AI quote and attribute facts from it?
Concrete facts an AI answer can quote and attribute to you.

Weekly monitoring, included in Pro
Know the week something breaks, not the quarter.
A release, a new theme or a CMS update can hide your content from AI crawlers while the site looks perfect in a browser. Pro re-scans your whole site every week, checks every link and emails you what changed: the score, the pages that dropped, the check that failed and the fix.
Monday
Score 91. Everything healthy.
Your fixes are done and AI crawlers can read every page.
Thursday
A release goes live.
The new theme loads navigation and product text with JavaScript. In a browser, nothing looks different.
Next morning
Siteiz re-scans every page.
It reads the site the way AI crawlers do, checks every link and compares with last week.
In your inbox
Score 91 → 74, and why.
The pages that dropped, the check that failed and the fix to ship. Before anyone asks why AI answers stopped mentioning you.
No AI guesswork: the same rules engine as the free scan, run every week.

FAQ
Questions, answered
Is the Siteiz scan free?
Yes. Scanning one page is free, with no account and no signup fee. You get the full A to F grade, the six pillar scores and the evidence behind them right away, and your top-ranked fixes when you add your email. To get every fix written up, buy the Fix Plan once for 1490 kr, or subscribe to Pro for 490 kr / month to cover your whole website, re-scanned every week.
What does the scan measure?
Six pillars: visibility, crawl access, machine facts, citability, actionability, and efficiency. Each is measured from your actual page, weighted by how much it affects AI readability, and combined into a single grade from A to F.
Do AI crawlers run JavaScript?
It depends on the crawler and the system. Many retrieval-oriented AI crawlers, such as GPTBot, ClaudeBot, and PerplexityBot, primarily consume the raw HTML response they receive rather than running a full browser session, so content added by JavaScript can be missing for them. Some AI systems can render pages. Siteiz measures this directly: it tests your raw HTML response separately from a browser-rendered version, so you see exactly what disappears when JavaScript is not executed.
My site ranks fine on Google. Does this still matter?
Yes. Googlebot renders JavaScript for classic search, so a page can rank on Google and still be unreadable to ChatGPT. The two systems read your site in different ways, which is why a good Google ranking does not tell you how you look to AI.
How long does a scan take?
About 60 seconds for a single page. You watch each step run: fetch as a crawler, render as a human, then analyze and grade.
What is in the paid Fix Plan?
Every fix your scan found for one page, ranked by impact, each written up with the exact code and apply notes, delivered as a polished PDF plus ready-to-paste fix files. It is a one-time 1490 kr with VAT included and instant delivery. Nothing renews.
Pro or the Fix Plan: which should I choose?
Choose Pro at 490 kr / month to keep a whole website AI-ready: one website, up to 50 pages per scan, steps and copy-paste code for every fix, a full broken link report, and a weekly automatic re-scan that emails you what changed. Pro renews monthly until you cancel. Choose the Fix Plan if you only need one page fixed once: you pay 1490 kr one time and keep the PDF and fix files, with no account.
